Cyproheptadine for dogs is an antihistamine used to control allergy symptoms. It is more commonly used in cats, though it may be prescribed to dogs, as well. In cats, cyproheptadine helps stimulate the appetite, but this does not happen in dogs that take the medication. Cyproheptadine is sometimes known by the brand name Periactin, and it can only be obtained with a prescription from a veterinarian, though it is not FDA approved for veterinary use. Side effects of the drug are typically minimal, which can make it useful for dogs that are prone to developing side effects when they use other antihistamines. If your veterinarian prescribes cyproheptadine, follow their instructions for use and dosage carefully and monitor your dog closely for concerning reactions or side effects. Here is what you should know about the uses, dosage, and side effects of cyproheptadine for dogs.

Cyproheptadine is used to treat allergy symptoms such as swelling, itchiness, and signs of atopy. In addition to being an antihistamine, it also can act as an anti-serotonin drug, which can be helpful in treating Cushing’s disease. This effect is felt more strongly by cats, which is why it is commonly prescribed as an appetite stimulant to felines. It is a particularly strong antihistamine, which is why dosage instructions must be followed closely. Because of cyproheptadine’s minimal side effects, it is usually prescribed to dogs that have had a negative reaction to other allergy medications.

The usual dosage of cyproheptadine to treat allergies in dogs is 0.15 mg to 1 mg per pound of body weight given twice a day. The drug is supplied in the form of 4 mg tablets or 2 mg per 5 ml syrup. You should follow your veterinarian’s instructions closely for dosing, as they may alter the dosage depending on your dog’s reaction to cyproheptadine. You should also follow your veterinarian’s treatment plan for the entire duration, even if allergy symptoms improve.

Cyproheptadine is generally safe for dogs when prescribed by a veterinarian; however, some side effects have been observed in dogs who take the drug. If you see signs of the following side effects, consult your veterinarian, as they may wish to alter the dosage or seek an alternative form of treatment.

Before giving cyproheptadine to your dog, make sure your veterinarian is aware of any other medical conditions your dog may have, especially glaucoma, prostate gland enlargement, heart failure, and gastrointestinal obstructions, and notify your veterinarian of any medications your dog is taking, as these may decrease the effectiveness or react poorly with cyproheptadine. Caution should be used when giving the medication to pregnant or lactating dogs. As with all medications, there is a risk of allergic reaction that can lead to anaphylaxis, a potentially life-threatening condition. If you see the signs of an allergic reaction in your dog, including swelling, hives, itchiness, difficulty breathing, or other allergy symptoms, contact your veterinarian immediately and stop giving cyproheptadine to your dog.
